HKT1 — Triticum aestivum
Summary
TRAESCS2D02G428400, the bread wheat gene TaHKT1 on chromosome 2D, encodes a transmembrane cation transporter with sodium and potassium transporter activity, belonging to the TrkH-K_transport family. This gene is associated with salinity response, sodium ion membrane transport, potassium ion homeostasis, and osmotic response. It has been linked to numerous agronomically important traits including grain yield, grain protein content, spikelet number, seed size, germination rate, seminal root length, coleoptile length, net photosynthetic rate, chlorophyll content, cell membrane stability, and tolerance to drought, heat, cold, and stripe rust. The encoded protein localizes to the plasmalemma, Golgi membrane, ER membrane, and mitochondria. Studies of related genes in other species link the family to salt tolerance, sodium accumulation and distribution, ion homeostasis, and potassium nutrition.
